Problem :
My code is below.
I need to get the landmark value out. I see it is in the same object as top, left, right, bottom. And these four values I take in the probe function are
obj_meta = pyds.NvDsObjectMeta.cast(list_obj_meta.data)
rect_params = obj_meta.rect_params
x = rect_params.left
y = rect_params.top
w = rect_params.width
h = rect_params.height

Because I’m seeing it saved in the object, but when I get the lardmark by:
landmark = rect_params.landmark
Then it says there are no landmarks in rect_params.

In addition, I tried to get obj_meta.landmark but it also said it was not there, please help me

How to get landmard value?

[junshengy]

1. Can you get landmarks from native post-processing?

2.If the answer to the above question is yes, do you want to get the corresponding landmark in Python?
If you want get landmark in python, corresponding python bindings need to be added.

This is a sample for facial landmark.

NVIDIA-AI-IOT/deepstream_tao_apps/blob/release/tao4.0_ds6.3ga/apps/tao_others/deepstream-faciallandmark-app/deepstream_faciallandmark_app.cpp#L400

This is another sample for add meta python bindings.
